IIC-DR-22: Isolated Current Converter

The Isolated Current Converter accepts a 24Vdc power supply (nominal). A 0-200 mA input signal is converted to a 4-20 mA current output. Span and zero are user adjustable. Diagnostic LEDs indicate power and operational status. The output LED is on when the load, input signal and power supply are connected. The LED flashes when the load is disconnected. The load can be floating or grounded. The unit is available in a DIN rail mount housing.


  • As part of a load management strategy for a marine propulsion system, the unit converts a 0-200 mA load signal from a diesel engine control computer to a 4-20 mA signal for a variable pitch propeller control system.
